Association of Age-related Macular Degeneration With Mortality in Patients With Acquired Immunodeficiency Syndrome; Role of Systemic Inflammation.

ABSTRACT: PURPOSE:To evaluate the relationships among age-related macular degeneration (AMD), mortality, and biomarkers of systemic inflammation in patients with acquired immunodeficiency syndrome (AIDS). DESIGN:Case-control study. METHODS:In participants with intermediate-stage AMD at enrollment in the Longitudinal Study of the Ocular Complications of AIDS (LSOCA) and 2:1 controls matched for age and sex, cryopreserved baseline plasma specimens were assayed for biomarkers of inflammation, including high-sensitivity C-reactive protein (CRP), interleukin (IL)-6, interferon-? inducible protein (IP)-10, soluble CD14 (sCD14), soluble CD163 (sCD163), kynurenine/tryptophan (KT) ratio, and intestinal fatty acid binding protein (I-FABP). Main outcome measure was mortality. RESULTS:The study included 189 patients with AMD and 385 controls. In the unadjusted analysis, AMD was associated with mortality (hazard ratio [HR] 1.48; 95% confidence interval [CI] 1.02, 2.15; P = .04). In an adjusted analysis, CRP (HR 1.36; 95% CI 1.08, 1.71; P = .009), IL-6 (HR 1.45; 95% CI 1.11, 1.90; P = .006), and IP-10 (HR 1.41; 95% CI 1.08, 1.84; P = .01) were associated with mortality. In a Cox regression analysis adjusted for human immunodeficiency virus load, blood CD4+ T cell level, CRP, IL-6, and IP-10, the association of AMD with mortality was attenuated (HR 1.08; 95% CI 0.73, 1.59; P = .70), primarily by the addition of the inflammatory biomarkers. CONCLUSIONS:These data suggest that the increased mortality observed in patients with AIDS with AMD is, at least in part, a result of systemic inflammation.

Project description:BackgroundEpidemiological data show that myeloproliferative neoplasms (MPNs) are associated with increased risk of neovascular age-related macular degeneration (AMD). However, knowledge about the retinal findings in these patients is lacking. This study was conducted to examine retinal ageing and the prevalence of a hallmark of AMD; drusen, in patients with MPNs. Further, we examine the role of chronic systemic inflammation, considered central in both AMD and MPNs.MethodsIn this single-centre cross-sectional study, we consecutively enrolled 200 patients with MPNs. The study was divided into three substudies. Firstly, we obtained colour fundus photographs from all patients to evaluate and compare the prevalence of drusen with the published estimates from three large population-based studies. Secondly, to evaluate age-related changes in the various retinal layers, optical coherence tomography images were obtained from 150 of the patients and compared to a healthy control group, from a previous study. Thirdly, venous blood was sampled from 63 patients to determine the JAK2V617F allele burden and neutrophil-to-lymphocyte ratio (NLR), a marker of systemic inflammation, in MPN patients with and without drusen.FindingsPatients with MPNs had an increased risk of having large drusen compared to the three population-based studies OR 5·7 (95%CI, 4·1-8·0), OR 6·0 (95%CI, 4·2-8·4) and OR 7·0 (95%CI, 5·0-9·7). Also, we found that the retinal site of drusen accumulation - the Bruch's-membrane-retinal-pigment-epithelium-complex was thicker compared to healthy controls, 0·43μm (95%CI 0·17-0·71, p = 0·0014), but there was no sign of accelerated retinal ageing in terms of thinning of the neuroretina. Further, we found that MPN patients with drusen had a higher level of systemic inflammation than MPN patients with no drusen (p = 0·0383).InterpretationPatients with MPNs suffer from accelerated accumulation of subretinal drusen and therefore AMD from an earlier age than healthy individuals. We find that the retinal changes are located only between the neuroretina and the choroidal bloodstream. Further, we find that the drusen accumulation is associated with a higher JAK2V617F allele burden and a higher NLR, suggesting that low-grade chronic inflammation is a part of the pathogenesis of drusen formation and AMD.FundingFight for Sight, Denmark and Region Zealand's research promotion fund.
